What integrated would you recommend for summer amp?

Hey all, I'm feeling sinful for running my Primaluna Dialogue HP integrated all summer long.  It pumps out modest heat but it does push the A/C to run longer and all that seems wasteful. 

Thing is, I want to keep life simple and within my means right now. So, I'm thinking the budget needs to be ~$1k new/used.  Here's my setup now: 

• Primaluna integrated
• Klipsch Forte III loudspeakers
• Manley Chinook phono pre
• Technics 1200 GAE turntable
• Kiseki Purpleheart cartridge
• Bluesound Node (Tidal mostly)
• Old Rotel CD player
• Doge Audio Tube DAC
• Analysis Plus cabling
• REL T9i subwoofer

Let the recommendations fly!
